My Lord of the Sea, Please Do Your Work!

The Lord of The Sea — riding above the waves, calling upon the life of the seven seas, and even the beasts of the abyss listens to his callings. As the acting Lord of the Sea and possessing godly powers, I, Hai Ming, have to infiltrate the Magic Academy while pretending to be a normal student and doing ‘espionage' work?? How degrading! But for the sake of the world of magic, I have to fight back against the evil demons! I'll have to work very hard! My Lord of the Sea, please do your work! (Source: Bilibili, translated)
